This error occurs because the output directory you selected is the same as the input directory or the software's working directory, which is not allowed to prevent overwriting source files.
Solution:
In the main interface, click the "Output Dir" button (or the folder icon next to it).
Select a different folder for saving the processed videos. For example, you can create a new folder named _video_out in your software's root directory (D:/AI_Tools/pyvideotrans/_video_out).
Alternatively, leave the "Output Dir" field empty. The software will automatically use the default output folder (_video_out) located in your software's installation directory (D:/AI_Tools/pyvideotrans/_video_out).
